I like the idea of specifying aliases rather than handle ranges, etc., 
if that is feasible. I also agree that we want this interface to allow 
this specification at create time, but then we want to use our existing 
scheme for long-term metadata storage (e.g. just keep the handles).

Regards,

Rob
